use file path alias in cd

orschiro · 2011-09-27 08:58:52

Hello guys,

I have an alias alias personal='cd /media/personal/files/' but I would love to use this inside other bash commands such as cd.

For example:

cd personal/music
rm personal/doc/file.txt

This would be really dreamlike. Is something like that achievable with bash?

Regards

I may be wrong, but AFAIK it's not. Aliases point to commands, while cd-ing can affect only dirs.

Edit: Wouldn't a symlink be enough here?

In bash you can put e.g.

shopt -s cdable_vars
export apps="/home/karol/test/apps"
export usb="/media/usb"
export cachedir="/var/cache/pacman/pkg"

in your ~/.bashrc and then

[karol@black ~]$ cd apps
/home/karol/test/apps
[karol@black apps]$

I'm not quite sure if this solves my problem.

[bashrc]
shopt -s cdable_vars
export personal="/media/personal/robert"

Let's assume I want to open a folder 'share' in personal.

I would do 'cd personal/share' but bash cannot find the directory.

In ~/.bashrc set

test="/home/karol/test"

then

[karol@black ~]$ echo $test
/home/karol/test
[karol@black ~]$ cd $test/apps
[karol@black apps]$

That works better. Thank you.

However, I guess completion and using test instead of variable $test is impossible?

'test' is just a variable, you need to call it like any other variable -'$test'.
I've heard that zsh is the ultimate interactive shell, you may want to try it out.
